Phytodecta.] PHYTOPHAGA. 318 
Scotland, local, Solway, Tweed, Forth, Dee, and Moray districts. Varieties occur on 
the Continent, more especially in Norway and Sweden and Finland, with the thorax 
and elytra marked with black spots ; I have not seen any of these varieties amoung 
our British specimens. 
(P. affinis, Gyll. This species is extremely doubtful as British, and 
requires further confirmation before it can be admitted into our lists ; 
one specimen only was found more than twenty years ago by Mr. C. 
O. Waterhouse among some beetles belonging to Mr. Cocking of Norfolk, 
who had found it among some sweepings belonging to Mr. Winter ; 
the latter gentleman did not remember its capture, but had no doubt 
that he had taken it himself with Leptura sanguinolenta (also in Mr. 
Cocking’s box) in the Norfolk fens. P. afjinis resembles the var. 
decempunctata of P. viminalis, but may be distinguished by its black 
thorax, which is also less contracted in front, and by the interstices of 
the elytra being destitute of punctures. There appears to be a variety 
with the tibie and sides of thorax reddish. (See Ent. Monthly Mag. 
1. 278.) 
GASTROIDEA, Hope. (Gastrophysa, Redt.) 
This genus contains about fourteen species, which are found in 
Northern and Central Asia, North America, and Europe; of the three 
European species two occur in Britain ; they are small brightly coloured 
species with the thorax almost straight at apex and margined at base ; 
the antennz have the last six joints thickened ; the elytra are closely 
and irregularly punctured, and the tibize are strongly produced into a 
tooth externally at apex ; the tarsal claws are simple ; the larvee appear 
much to resemble those of Melasoma in general form. The abdomen 
of the impregnated female swells to a large size, and often far exceeds 
the elytra; hence the names given to the genus.
